1 UNITED STATES PATENT OFFICE I I ALBERT H. LE FEVER, OF NEW YORK,1 T.Y.

TRANSMISSION DEVICE.

Specification of Ietters I'atent. Patented Dec. 24, 1912. Applicationfiled. August 20; 1910. Serial No. 578,165.

To all whom 'it may concern:

Be it known that I, ALBERT H. LE FEVER, a citizen of the United States,residing'at Hotel Belleclair, New York city, in the county of New Yorkand State of New York, have invented certain new and useful Improvementsin Transmission Devices, of which the following is a-specification,reference being had therein to the accompanying drawing.

My invention relates to improvements in transmission devices and hasparticular reference to means for transmitting power more eflicientlyand without the use of gears, belting, friction devices, or similarapparatus.

In the accompanying drawings I have illustrated in side elevation inFigurel an apparatus illustratingan. application of my invention. Fig. 2is a plan view of the same looking from right to left at Fig. 1', andFig. 3 is another plan view showing the operating parts of the device ina different position.

The form of device illustrated in the accompanying drawings is adaptedto transmit power at a two to one ratio.

4: and 5 are uide-ways mounted in the position shown by any suitablemeans such as the ring 13, so as to provide slide bearings for theblocks 6 and 7 pivotally secured at opposite ends of the lever 8 asshown at -10.

The lever 9 is preferably keyed or otherwise secured to the axis i 7Copies of this patent may be obtained for five cents each,jby addressingthe Commissioner Washington, D. O. a

10 and the same applies to the lever 8, and

is provided with a shaft 11 which is also secured thereto. The block 7is axially mounted on the opposite end ofthe lever 8. The shaft 12 isalso keyed or otherwise secured to the frame piece 5 of the guide 5.From this arrangement it will be seen by looking at Fig. 3 that as theshaft 11' is rotated rightwardly, the block 6 travels upwardly as theblock 7 travels downwardly thereby imparting a rightward movement to theframe structure as a whole secured to. the shaft 12. It will also beobserved that Q the shaft 12, only rotates about half as fast as theshaft 11 thus reducing thespeed of v rotation in transmission and ofcourse it. naturally follows that by applying the power to theshaft 12,the speed.at the shaft 11 will be doubled. It will also be'understoodthat by connecting the'shaft 12 of one device to the shaft 11 of asimilar device that the ratio ofaincreased or reduced speed can agreater number of guideways may be provided for for varying-the increaseor reduction of speed and that the general de-. sign and mechanicalconstruction of the debe enlarged. It will also be understood that yicecan be elaborated and modified according to the special requirements forwhich the device is to be used. In fact various modifications can bemade without departe ing from the spirit of the invention as set forthin the claim. I f

Having described my invention, what I claim as new, and desire to secureby Let ters Patent is:

Aitransmission device comprising a frame secured to a shaft, said framehaving superimposed slide bearings at right angles, a crankhaving oneleg longer than the other,

a block at the free extremity of the long.

leg of said crank adapted to engage and slide within one of saidbearings, another block at the opposite extremity and begage I and slidewithin the other of said bearings, the free extremity of the short legof said crank secured to another shaft.

In testimony whereof I aflix my signa-' ture in presence of twowitnesses. Y
